| 摘 要： | 采用高压汞灯为光源，考察了H2O2与UV／TiO2协同体系对酸性品红的降解效果。结果表明：H2O2提高了UV／TiO2光催化降解酸性品红的速率。同时，研究了影响纳米TiO2光催化降解酸性品红的主要影响因素。实验结果表明：初始PH值等于7时，光催化效率最佳；随着初始浓度的增加光催化降解效率降低；TiO2的最佳用量为0．2g/L。

| Abstract: | A high-pressure mercury lamp was used as the light source.The degradation effect of the synergistic system of H2O2 with UV/TiO2 on acid magenta was studied.The experiments demonstrated that: the efficiency of UV/TiO2 photocatalysed degradation of acid magenta can be improved by H2O2.Meanwhile,the effect of various factors on the photocatalytic degradation of acid magenta was investigated.The experimental results of this study showed that: the degradation efficiency of photocatalyst is the best while the initial pH is 7,and it decreases as the initial concentration increases.0.2 g/L of TiO2 was selected as the optimal amounts for the experiment. |
